Embodiment
Fig. 1 shows the extruder system 100 for forming multilayer rubber complex in once-through operation.The extruder system
System includes at least two extruders 110,120.Usually using screw extruder, although ring extruder can be used.Fig. 1 is shown
Backpack extruder system, wherein there are four screw extruders 110,120,130 and 140 for being used for forming multilayer composite.
These extruders need not mutually be born（That is, extruder is stacked to together, towards equidirectional).These extruders can face
The construction in face and arrange, it means that extruder is arranged such that they are opposed facing, and wherein head is located at each extrusion
Between machine.
Each extruder 110,120,130,140 is typically to be made of the main body 11 of cylinder form, which accommodates
Internal screw rod 12.When screw rod 12 rotates, rubber is set to advance forwardly past main body.The rubber when being processed by screw rod 12
It is grated.Each extruder 110,120,130,140 usually has the different rubber or elastomer being extruded.Each rubber
Or elastomer stream leaves each extruder screw and enters the respective flow channel 210,220,230,240 of extruder head component 200
In.Therefore, for each extruder screw, there are a flow channel.Each elastomer stream leaves flow channel and is injected into splicing
In bar assembly 300.As shown in Figure 2, the shaping bar that bar assembly 300 includes the rectangle with detachable insert 311 is spliced
302.The shaping bar of the rectangle has the longitudinal axes L that the width along this extends.When the shaping bar insert insertion rectangle
When 302, a plurality of runner 310,320,330,340 is formd.Usually by different types of elastomer by each extruder 110,
120th, 130,140 injection, the stream of each extruder are injected separately into runner 310,320,330,340.Fig. 3 show splicing bar and
The section of runner.The back side 350 for splicing bar assembly 300 has at least one groove 370 being located between two runners 310,330.
The back side may include additional groove, these grooves are spaced-apart by each runner.The function of groove is excess of the trapping from a passage
Stream, so as to prevent excessive stream from flowing into adjacent passage.If compound is rested in groove, then its hardness when it cures
It will increase, so as to form a type of " O-ring " sealing, which prevents more compounds from passing through the gap.Therefore, spell
Groove in the back side of narrow bars prevents the stain of compound or undesired leaks into adjacent flow channel.Compound from
After opening runner 310,320,330,340, stream passes through mould 400, so as to form multilayer composite.
In cleaning or inspection, the state of groove is the indicant of extrusion performance.Therefore, if groove is empty, this is represented should
Component is fluid-tight, i.e., does not leak.If groove is elastomer-filled, this is to show potential extrusion problem and prompt
The warning that should be taken corrective action.
According to description presented herein, change in the present invention is even more feasible.Although in order to illustrate the present invention's
Purpose shows some representative embodiments and details, but it will be apparent to one skilled in the art that without departing substantially from this hair
Can various alterations and modifications can be made in these embodiments and details on the premise of bright scope.It is therefore to be understood that can be with
Change is made in described specific embodiment, its model that will all want in the present invention being defined by the appended claims
In enclosing.
